GUIDE SPECIFICATION

FOR THE POWER COMMANDER

SERIES 900A ELECTRONIC LINE VOLTAGE REGULATOR

1.0General

This specification describes the electrical and physical aspects of the Power Commander - Series 900A Electronic Line Voltage Regulator. All systems are designed and manufactured to assure maximum reliability, flexibility, serviceability and performance. The Power Commander - Series 900A uses seamless electronic control to provide 1% output regulation. The output is adjustable + 10% from nominal with an internal potentiometer. If a voltage transformation is required, Controlled Power's Ultra-K - Series 600K K-rated isolation transformer must be utilized. The Ultra-K will step the voltage up or down to the desired level, give isolation, and provide transient and noise attenuation.

The system shall be Controlled Power’s Power Commander Series 900A or Owner / Engineer approved Equal.

2.0Standards

The Power Commander Systems are designed and manufactured in accordance with the following:

- Institute of Electrical and Electronic Engineers (IEEE 597)

- National Fire Protection Association (NFPA) 70, National Electrical Code (NEC)

- Underwriters Laboratory (UL 1012)

3.0Performance Specifications

3.1System Rating: The system shall be rated at ______KVA.

3.2Input Voltage - Nominal A.C. input voltage shall be ______Volts, _____ Phase.

3.3Output Voltage - Nominal A.C. output voltage shall be ______Volts, _____ Phase. (Note: If output voltage is different than input voltage, Controlled Power’s Ultra-K is needed.)

3.4Output Voltage Regulation - Shall be + 0.5% for input voltage fluctuations of +10% to -25%.

3.5Remote Sensing - The output voltage shall be able to be sensed and regulated at the load automatically compensating for line and wire losses due to long distances to the load.

3.6FrequencyRange - Shall be 57 to 63 Hz for 60 Hertz models, or 48 to 52 Hz for 50 Hertz models.

3.7OutputVoltageAdjustmentRange - Shall be adjustable to + 10% with internally located potentiometer.

3.8Correction Time - Shall be 5 cycles or less under worst case conditions.

3.9Efficiency - Shall be 95% typical.

3.10Power Factor - Shall be typically 95% at full load.

3.0Performance Specifications (Continued)

3.11Harmonic Content - Less than 5% THD shall be added.

3.12Overload Capability - Shall be 500% for 10 seconds, 1000% for one cycle. Shall conforms to IEEE 597.

3.13Audible Noise - Shall be less than 60dBA @ 1 meter.

4.0Transformer

4.1Transformers shall be buck-boost dry type, convection or fan air cooled, 600 volt class.

4.2The transformer shall be electrically and magnetically regulated with no moving parts.

4.3All transformer windings shall be class N (200 C) insulated copper.

4.4A class N installation system shall be utilized throughout with operating temperatures not to exceed 115C over a 40C ambient temperature.

4.5Transformer core manufactured shall utilize M-6 grade, grain oriented, stress relieved silicon transformer steel.

4.6Interface terminals shall be provided for input and output conductors.

4.7All leads, wires and terminals shall be labeled to correspond with circuit wiring diagram.

4.8Transformers shall be vacuum impregnated with an epoxy resin.

5.0Cabinet Construction

5.1Cabinet shall be attractive, functional, NEMA type 1 general purpose indoor enclosure.

5.2Cabinet shall be manufactured from heavy gauge steel. Base sub-structure shall be adequate for fork lifting.

5.3Dimensions shall be: ______”W x ______”D x ______”H.

5.4Texture baked on paint finish with proper pre-treatment shall be provided.
